BEARNG.

Application led October 30, 1925. Serial No. 65,797.

While the construction of an ordinary bearing may appear a simple matter, it has been found difhcult by even those skilled in the art, to provide satisfactory bearings for small high-speed motors or generators suoli as are in more or less general use. While the present invention may be applicable for general purposes, it is particularly adapted for small motors su-ch as are usually known as fractional horse power motors. are in many instances placed on machines which are used by persons not familiar with machinery and are expected to operate for lone periods without attention such as oiling or c eaning. For this reason@ have produced the bearinon which forms the subject matter of this application and `which is intended to give maximum lubrication over a long period of time and to have but little friction or wear.

@ther object-s of this invention are to provide an improved bearing with novel journallubricating means; to provide a bearing having means for preventing dirt or dust from reaching the moving parts; to provide a bear- 1-1 of li`igure`2; and

Figure 2 1s a sectional view taken on the line 2-2 of Figure 1.

to rl`he bearing housin 3, as shown in these drawings, may be attac ed to the motor frame 4t in any desired manner or in some instances may be made integrally therewith. Plllhe housing 3 is provided with a transverse web or support 5 having a central .aperture 6 for the bearing sleeve or bushing 7. rl`he web or support 5 is preferably made relatively narrow so that it engages with the central portion of the sleeve 7, the ends of which project somewhat beyond the web, therebypermitting the sleeve to have sufficient play or give so that it is free to align with the journal or bearing portion 8 of the motor shaft 9.

The housing 3 has a threaded hole 10 in the u per portion thereof for receiving a screw or v P ug ll. The lower end of the plug is preferrIphese motors ing 'having means tending to prevent the oill Figure 1is a sectional view taken on the line ,will be constantly lubricated as long as oil is supplied to the housing. llt will be noted that ably solid and passes through a hole 12 in the web 5 and engages with a hole 13 in the sleeve in order to hold the sleeve in proper posiion. t lt will be noted that the web or partition 5 1s cut away at the top and bottom, but divides the housing in a general sense into outerand inner connected chambers 11i and 15. The housing 3 is also preferablyprovided with an aperture 16 having a cap 17 and providing means for introducing any suitably absorbent material 18, such as felt, wool or the like into the chamber llt and for access to the bearing.

The plug or screw 11 has a central oil hole 19 with one or more lateral passages 2() which open out above the partition 5 so that the oil will pass out into ther upper portion of the housing instead of passing directly to the bearing surfaces.

rlhe housing 3 also has a threaded hole 21 for receiving a plug 22 which carries a cylindrical .wick 23, which is pressed upwardly by a spring 24.J rllhe wick passes through a hole 25 in the web 5 and through a hole 26 in 80 the bearing sleeve 7 and engages with the journal 8.

The shaft 9 has a collar 27 with an outwardly projecting ange 28 which is engaged by a disk 29 preferably made of nbre or other suitable bearing material.

When the oil or lubricant is introduced through the hole 19, it passes out through the lateral passageways 2O into the housing 3 where the major portion will be absorbed by the brous packing or absorbent. material 18, butany excess will pass down to the bottom of the housing. Yl`his lubricant will be ab sorbed by the wich 23 and will be carried upwardly to the bearing so that the bearing when a motor starts in operation, heat will be generatedand as the bearings b come warm, theyrvill tend to warm the lubricant so that it willjoass more freely to the bearing as it is neede .ein excess lubricant which tends to creep inwar ly along the journal will be thrown outwardly into the chamber 15 by the centrifugal action of the ring 28 and disk. 29 which rotate with the shaft. llt will thus be seen that 'these parts not only serve to protect the commutator armature from oil, but asfi serve to take up the end thrust of the s a t.

l have found that with this arrangement motors may be run for relatively long perifurthermore, there is little danger of injury to the bearing by any dirt or the like which may be in the lubricant as particles of this character will be taken out by the fibrous material and wick.

Having thus described my invention which however l do not wish to limit to the exact construction herein shown and described, except. as specified in the following claims, what ll claim and desire to secure by Letters Patent is:

1. ln a bearing of the character set forth, the combination ot a housing having a transverse integrally formed supporting member extending from one wall of the housing to the opposite wall and dividing the housing longitudinally into two chambers which are connected by a passageway under the supporting member, a bearing sleeve engaging with a hole in said supporting member, a threaded plug projecting through the housing and supporting member and engaging with said sleeve, said plug having a hole for introducin'g lubricant. into the upper portion of the housing, fibrous material in one of said chambers and a wick projecting upwardly from 'the lower portion of the housing and adapted to engage with the shat't which engages with said sleeve.

2. The combination of a housing having a transverse partition forming outer and inner chambers which are connected above and belowV the partition, a bearing sleeve engaging with a hole in said partition, a shaft engaging with said sleeve, a plug projectlng through the outer wall of the housino4 and the partition and engaging with a hole in the sleeve, said plug having an oil inlet passageway leading to the top of the housing. a plug in the bottom of the housing, a springpressed wick carried by said plug and projecting upwardly through the partition and sleeve and engaging with the shaft, and librous material in the outer chamber.

' 3. A bearing con'iprising a housing having a central partition wihh a hole therethrough, a sleevein said hole for engagement with a shaft, said sleeve having holes in the top and bottom thereof, a plug extending down through the top of the housing and through the partition and engaging with the top hole in said sleeve, a passageway through the plug leading to the housing, absorbent wool in said housing, and a wick mounted'in the lower portion ot' the housing and projecting upwardly through the bottom hole in said sleeve, the arrangement being lsuch that substantially all of the lubricant must pass through the wick to thebearing.
